Abstract

A simple device, Frequency Tracer (FT), for ultrashort light pulse duration and chirp simultaneous measurement is introduced. FT operation is based on the second-harmonic autocorrelator beam two-dimensional image analysis (time versus frequency), and it is able to evaluate the temporal phase variation over femtosecond pulse duration. The spectral information of fs pulse in FT originates from the angular divergence of a second-harmonic signal beam, and there is no need in using the spectral apparatus. Femtosecond pulses duration and chirp measurements of the Ti:sapphire laser system multipass amplifier (MPA) during adjustment of compressor pair of gratings were done.
